OIL-MAT.

SPECIFICATION forming part of Letters Patent No. 315,126, dated April '7, 1885.

Application filed January 31, 1885. (No model.)

To all whom it may concern:

Be it known that I, WILLARD W. OLooK, of La Grange, in the county of Troup, State of Georgia, have invented a certain new and useful Improvement in Mats, of which the following is a description sufficiently full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is an isometrical perspective view of my improved mat; Fig. 2, a vertical transverse section of the same, taken on the dotted line 00 00 in Fig. 1; and Fig. 3, a longitudinal vertical section taken on the dotted line 2 z in Fig. 1.

Like letters of reference indicate corresponding parts in the different figures of the drawings.

My invention relates to that class of mats which are employed in cottonseed-oil presses and it consists in a novel construction and arrangement of the parts, as hereinafter more fully set forth and claimed, by which a more effective and otherwise desirable article of this character is produced than is nowin ordinary versant with such matters from the following explanation, its extreme simplicity rendering an elaborate description unnecessary.

In the drawings, A represents the upper leaf, B the lower leaf, and G the handle.

Each of the leaves consists of a rectangular body, m, composed of thin sheet steel, iron, or other suitable metal, and provided on its back or outer side with a series of longitudinal grooves or channels, d, extending its entire length. The body an of each leaf is made tapering, or slightly narrower at one end than at the other, to fit the boxes of the press, its widest end being upset or turned over and riveted to the body, as shown at v, to receive ajoint-rod, l.

A raised oval or half-round flange, t, extends longitudinally the entire length of the body, at either side thereof, being secured thereto by proper rivets or screws; and disposed transversely of the body at intervals between the said fianges there are a series of oval or half-round ribs, f, also securely riveted or screwed to the body, the flanged and ribbed side of the leaf constituting its face and the grooved side its back.

Opening through the body of either leaf from the bottoms of the grooves d into the spaces between the ribs f there are a series of holes or oil-ducts, k, for conveying the expressed oil through the body into the grooves or channels d. Each of the bodies at is provided with two slots, r, at its widest end, and inserted in either of these slots there is a link, D, pivoted or jointed to the rod Z, the links of the upper leaf being respectivelyjointed to those of the lower leaf by the bars E.

The handle 0 is disposed horizontally between the bars E, being centrally supported on a suitable rod or journals, 4

The cross-ribs f and side flanges, t, are made of iron, steel, or other suitable metal, and may be formed integral with the body at, if preferred, either by casting, rolling, or striking the same up in dies. The grooves or channels d mayalso be formed by proper milling or cutting tools; or they may be formed by rollers or struck up by means of dies.

The holes are countersunk or slightly enlarged at their outer ends, where they open into the channels d, and, if deemednecessary, they may also be countersunk at their opposite ends;

The handle 0 may be rigidly connected with the bars E, or loosely journaled between the same, as desired, although I deem it preferable to journal the same, so that it will turn readily on the rod 7; and connect the rod rigidly to the bars.

The ribs and flanges prevent the cottonseed meal in the bags or sacks from becoming displaced by the action of the press, thereby enabling it to perform its work with greater facility and inore effectively than when the ordinary mats are used.

It will be understood that the size of the mat should correspond with the press on which it is employed; also, that in its use the ribbed faces of the leaves are to be placed adjoining each other, the oil passing through the holes k into the channels d, and being thereby conducted into the ordinary receptacle for the same.

I do not con fine myself to the use of the side flanges, t, as they may be omitted, if desired, nor to forming the ribsf straight or arranging them in regular order, nor to makingthe ribs and flanges oval or half-round. nor to jointing the links D to the leaves, as described, as all of these features may be varied considerably Without departing from the spirit of my invention; neither do I confine myself to DIO- viding both of the leaves with ribs, holes, and grooves, nor to using the leaf A as the superposed leaf, as it will be obvious that either leaf may be used in that position, as desired.

Having thus explained my invention, What I claim is 1. In a mat for cotton-seedoil presses, the combination of the following instrumentalities, to Wit: two foraminous leaves jointed or hinged together at one of their ends and provided on their adjoining sides or faces with a series of ribs or corrugations, and on their opposite sides or backs with a series of grooves or channels, substantially as described.

2. In a mat for cottonseed-oil presses, the leaf B, provided with the ribs f, holes or ducts 7c, and channels d, substantially as set forth.

3. The improved cotton-seed-oil-press mat herein described, the same consisting of the described.
